This brings us to an important lesson about formal verification and system design: the paradigm gap. Pure TLA+ is a beautiful event-driven way to describe the mathematically correct state of your system. However, the environments where these systems actually live (Java, Go, C++, or Rust) are fundamentally built around sequential threads, loops, and queues, just like our PlusCal model. The impedance mismatch between an event-driven specification and a sequential implementation introduces the risk of HOL blocking. Because modern programming languages make it so effortless to pause a thread and wait for a resource, it is incredibly easy for a system to fall into the blocking trap. We should be cognizant of this pitfall when implementing our designs.

In practice, the IOMMU defense has significant gaps. Many gaming motherboards ship with IOMMU disabled by default. Even when enabled, the IOMMU configuration is complex and many systems have misconfigured IOMMU policies that leave large physical memory ranges accessible. And critically, DMA firmware that successfully impersonates a legitimate PCIe device (e.g., a USB controller or a network card that the OS has granted IOMMU access to) can potentially access memory through the IOMMU using the legitimate device’s granted permissions.
